Suppose you and your two lab partners each read the volume of a sample of ñiquid in a graduate cylinder the three measurements you come up with are 211 mL,212mL and 212ML. the teacher tells you that the actual volume of the sample is 211 mL which of the following best describes your results? A. neither accurate nor precise

B. Precise but not accurate

C. accurate but not precise

D. both accurate and precise

I need help please

A is the correct answer

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
